A good window needs the same life as the building

Excerpt: China Economic Times

In recent years, China's urbanization process has developed rapidly.

According to the data released in 2022, the proportion of China's urban population in the national population (urbanization rate) is 65.22%, 0.5 percentage points higher than the end of 2021. At the same time, according to statistics, people spend at least 80% of their lives indoors, which makes people more aware of the importance of a quiet, comfortable and comfortable indoor living and working environment for physical and mental health, while the external window of the building is particularly critical because it bears the two-way role of indoor and outdoor communication and isolation.

The house has been living for decades. As an important part of the building facade - the window, it is not easy to replace. With the increase of living time, under the influence of external factors such as rain erosion, cold and heat alternation, pressure vibration, etc., the test of the quality of building external windows is also gradually increased, so the service life is also an important factor to verify the quality of a window.

There are many factors that affect the service life of windows, and the decisive factors are profiles and processes. The author learned that the aluminum-clad wooden window, as the representative of high-end window products, can meet the user's satisfaction in terms of both performance and service life due to its high requirements for profiles and high standards for technology.

For example, Senying Window Industry (stock code 301227), which has been established for 25 years, has been the first manufacturer of German aluminum clad wooden windows in China for more than 20 years since its first generation of products were applied. It is reported that it still has excellent performance.

According to foreign data, German aluminum-clad wooden windows can be the same age as buildings. This also depends on the characteristics of wood. The structure of wood is solid, which means that the service life is longer. At the same time, observing the existing ancient buildings in China, the wooden windows can still be used after hundreds of years, which proves that the wooden windows can reach a long service life as long as the structural design of the wooden windows is reasonable and properly maintained.

Especially at the moment of vigorously developing ultra-low and near-zero energy consumption buildings, the quality and service life of the building's exterior windows will directly affect the energy efficiency of the building in its service life. Therefore, it is particularly important that a good building should be equipped with windows, just like a good horse with a saddle.
